Abstract (en)
A tool driving device for cutting includes a spindle and an electric motor. A user carries the tool driving device by hand to use the tool driving device. The spindle has a holder for holding a tool for the cutting. The holder is disposed at a distal portion of the spindle. The electric motor rotates the spindle. A thrust bearing is attached to a housing of the electric motor. The spindle is contacted to the thrust bearing so that cutting resistance in a rotation axis direction of the spindle, transmitted from the tool to the spindle, is applied to the thrust bearing.
